People and Culture Business Partner - Org Design & Scale; Dutch speaking

About the role

Wellis is a fast-growing healthtech scale-up. As we grow, our team structures, role clarity, and operating model need deliberate design — not default sprawl. We're hiring a People & Culture Business Partner to own that: you'll design how the org is structured as we scale, and build the frameworks that let managers run good teams without a big People function behind them.

You'll be one of a small number of People people at Wellis. That means real ownership from day one - you're not implementing someone else's org design playbook, you're building it. It also means you won't have a large team around you; if you want structure and scale already built for you, this isn't that role.

You'll report to Veronica and work directly with team leads and founders on structure, headcount, and operating model decisions.

What you'll own

-

Organization design end-to-end: partner with team leads and leadership on team structure, role clarity, reporting lines, and operating model as we scale - not as a one-off project, but as an ongoing discipline.

-

Headcount planning: translate growth plans into concrete org structure and hiring sequencing, and hold the line when a request doesn't hold up.

-

Practical people frameworks: build manager responsibilities, role expectations, performance management, and onboarding - designed to be used, not filed away.

-

Project leadership: drive performance process rollouts, onboarding improvements, and manager enablement from idea to adoption.

-

Manager sparring partner: give team leads a straight, informed second opinion on team health, feedback, and development calls.

-

Data-informed decisions: use people data (Personio and beyond) to spot patterns and turn them into playbooks and templates managers actually reach for.
